ROTARY IBLOTTEB.

Application filed May 12,

T 0 all wit-pm it may concer /2 Be it'known that I, EDGAR L. GASTEIGER,

a citizen of the United States, residing in West Mead Township, near Meadville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in a Rotary Blotter, of which the following is a specification.

This device relates to rotary blotters and more particularly to a rotary blotting device adapted to be either permanently or removably attached to the cap of a fountain Another object is the provision of a blotting device, mounted on the end of a fountain pen cap at an angle, so that when in use the pen body will extend upwardly at an angle of approximately forty degrees, thus allowing the hand to grasp the pen without d anger of smearing the wet ink beneath and allowing the blotter to present a flat surface to the paper.

A further object is the provision of a rotary blotting member to be used in connection with a fountain pen, which may be easily and quickly removed to be replaced by a fresh blotting roll.

A still further object is the provision of a device carrying both a blotting element and a metallic scraper or erasing element, and which will be compact and neat in appearance, easily accessible, efi'icient in its use, strong. durable, and inexpensive to manufacture.

A better understanding of the invention may be had upon reference to the accompanying drawings in which 1- Figure 1 shows a vertical. s. :tional view oi"? a fountain pen cap, with my device, also in section.

Fig. 2 is a side elevation cf the upper end of a fountain pen cap, with the blotter cover and blotter removed and showing the shaft for supporting the blotter roll.

Fig. 3 is a modification of my device. partly in section, showing how it may be rcn'ioval'ily mounted upon a. pen cap.

Similar reference numeralsrefer to similar parts throughout the several views of the drawings.

T he fountain Jen includes a barrel I, having its cap 2, placed upon the rear thereof as is customary when the pen is to be used.

The cap 2, has its end wall thickened as indicated at 3, and has its top and outer side 1923. Serial No, 838,593.

depressed to form a concave surface 4. Upon one side of said concave surface is built a shoulder 5 carrying a shaft 6. This shaft extends upward from the shoulder and across the concave surface a, at an an gle of about fifty degrees and has at outer end a screw-threadedbore 7. A blotting roll 8, which may be formed of concentric layers of blotting paper, blotting stone or any absorbent material winch might be used for this purpose, having central longitudinal opening therethrough is positioned on the shaft 6 and held from removal by a semi-circular headed screw 9, which has its head knurled or otherwise roughened as shown, to form an abrading' surface useful in making erasures.

The upper end of the cap 2., is screw threaded as at 10, onto which a cover c. 11, is to be fitted thus covering and protecting the blotter when not in use.

On the surface of the cap 2, and near the lower edge thereof, is a score 15 which is to be aligned with a corresponding score 16 upon the barrel of the pen. These inn when brought together will place the blot ter in such a position that the natural halt turn given to the barrel by the finger when the same is inverted, will bring the flat surface oi the blotting element in the rect position for use.

In Fig. 3, is shown a modification of the device. In this form as shown, the device is made removable and consists of a head 3, having a concave top 4: as in the first form. Depending from the head 3 is a. cylindrical collar 12 which is of suficient diameter to permit its being closely over the top of the cap 2. Que or more bayonet slots 13 is, or may be, provided in the side of this casing for engagement with a lug 14: carried by the cap 2, tor the purpose of retaining the device upon the cap. The head 3 is screw threaded as at 10 onto which the cover cap 11 is screwed. The inaining structure is the same as that shown in Fig. 1.

Having thus described the invention, in accordance with the accompanying draw ings, it is to be understood that various changes and modifications may be made in the structure without departing from. spirit of the invention.

lVhat I claim is 1. The combination with a marking in llll") strument having means at one end thereof providing a concavity, of an abutment formed on the side wall of said concavity, an upwardly inclined shaft extending from said abutment, a blotting element rotatably mounted on said shaft, means for retaining said blotting element on the shaft, and a cover member for enclosing the same.

2. The combination with a marking instrument having means at one end thereof provided with a concavity, of an abutment formed on the side wall of said concavity and extending above the edge thereof, an integral upwardly inclined shaft extending from said abutment, a blotting element rotatably mounted on said shaft, screwthreaded means for retaining said blotting element on the shaft, and a cover member for enclosing the same.

3, The combination with a marking instrument having exteriorly screw-threaded means at one end thereof provided with a concavity, of an abutment formed on the side wall of said concavity, an integral upwardly inclined shaft extending from said and a cover member for enclosing the same. 4. The combination with a marking instrument having exteriorly screw-threaded means at one end thereof provided with a concavity, of an abutment formed on the side wall of said concavity, an integral shaft extending from said abutment having an upward inclination of approximately fifty degrees and a screw-threaded bore at its outer end, a cylindrical blotter element rotatably mounted on said shaft, screwthreaded means for insertion in the bore of said shaft for retaining said blotting element thereon, and an interiorly screwthreaded cover member for enclosing said blotting element.

5. The combination with a marking in strument having detachable means at one end thereof provided with a concavity, of

an abutment formed on the side of saidcon cavity, an integralupwardly inclined shaft extending from said abutment, a blotting element rotatably mounted on said shaft, means for retaining said blotting element on the shaft, and a cover member for e abutment and across said concavity, a cylin- -closing the same.

drical blotting element rotatably mounted on said shaft, screw-threaded means for retaining said blotting member on the shaft,

In testimony whereof, I aflix my signature hereto.

EDGAR L. GASTEIGER.
